Get next business day as string

I want to write a notification about the next business day. (monday-friday)
This should be done as a string

if(now.getDayOfWeek <= 4) {… next business day would be +1}
otherwise the next business day is monday.
But how can i format this number item as a string?

my system locale is German so it would be printed as (Montag instead of Monday etc.)

Thanks :slight_smile:
